- AUTO POWER-TRANSMITTING JACK.

Application filed January 28, 1922. Serial No. 532,408.

To all whom it may concern:

. Be it known that I, NnLsoN STANBROUGH, a citizen of the United States, residing at Ouray, in the countyof Ouray and State of Colorado, have invented certain new and useful Improvements in Auto Power-TransmittingJacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same;

The invention relates to apparatus whereby the engine of a. motor vehicle may be utilized for driving light. machinery such as corn shellers, threshing machines, straw stackers, sawing machines and the like, the apparatus being portable and adapted to jack up the rear portion ofthe motor vehicle to elevate the drive wheels which are thus free for operating the machinery to be driven, the power being-transmitted through the device forming the subjectmatter of the present invention.

Other objects and advantages will be apparent and suggest themselvesasthe nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet difierent conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure 1 is an elevationof an apparatus embodying the invention, showing an application thereof,

Figure 2 is a top plan view of the apparatus,

Figure 3 is a front view thereof, the supporting wheels being in position to admit of ready transportation of the apparatus, and

Figure 4 is a vertical transverse section on the line 4-4: of Figure 1, looking in the direction of the arrows.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The apparatus comprises a base, which in the present instance is shown as comprising longitudinal bars 1 and connecting end bars 2. The base is mounted upon wheels 3 to admit of ready transportation of the apparatus from one place to another. The wheels 3 are detachably mounted upon axles 4: to admit of their removal when the apparatus is set up for use. Set collars 5 applied to opposite end portions of the axle 4i prevent longitudinal displacement thereof and maintain the same in given position. The wheels are retained in place by means of set collars 6 which when removed admit of the wheels being detached. Short chains 7 or like parts, are provided at the corners of the base and are adapted to receive stakesor pins 8 whereby the apparatus ismade secure when in operative position.

Uprights 9 rise from the side bars 1 of the base and receive a transverse shaft 10 which is provided with a middle pulley 11 and end pulleys 12, longitudinal displacement of the shaft 10: being prevented by means of set collars 13. Braces 14; connect the upper ends of the uprights 9 with the rear corners of the base. Other braces 15 connect the uprights 9 with the front corners of the base. Each of the braces 15 is provided in its length with projections 16 inthe form of hooks-for a purpose presently tobe described. Uprights 17 are disposed at the front corners of the base and are connected at their upper ends by means of a cross piece 18. Stays 19 connect the upper ends of the uprights 9 and 17 on the same side of the apparatus. Each of the uprights 17 is provided with a plurality of openings 20 in its length. I.

Levers 21 fulcrumed to the uprights 17 have hooks 22 at their outer ends and their inner ends are adapted to engage selected projections 16 whereby to hold the hooked ends 22 at the required elevation. The levers 21 are vertically adjustable on the uprights 17 and are retained in the adjusted position by means of bolts 23 or like parts which form the fulcrum therefor. The bolts 23 are adapted to pass through any one of the openings 20 and corresponding openings formed in strips 2O secured to the uprights 17.

When it is required to transport or move she apparatus, the wheels 3 are placed in position on the ends of the axles 4c and after the apparatus has been properly positioned, the wheels 3 are removed and the apparatus made secure by driving stakes or pins 8 into the ground through links of the chains 7. The motor vehicle 24:, whose engine is to be utilized for driving the machinery to be operated, is adjusted with reference to the apparatus so that the hooks 22 of the levers 21 engage the rear drive axle, after which the levers 21 are manipulated to elevate the rear portion of the motor vehicle to lift the drive wheels 25 clear of the ground whereby power may be taken therefrom for driving the shaft 10. A drive belt 26 is fittedto each of the drive wheels 25 and to the corresponding pulleys12 so that-when theengine of the motor vehicle is running motion is chine tobedriven.

' What is claimed is:

- 1. Amotor vehicle power transmitting jackcomprising a base, uprights thereon, a shaft mounted in the uprights and provided with pulleys adapted to receive and transmit power, braces between the uprights and/base and provided in'their' lengths with a plurality of projections, other uprights rising from the'base, and levers adjustably fulcrumed on the. last mentioned uprights and adapted to engage selected projections of the braces and adapted to engage the drive axle of the motor vehicle and elevate the drive wheels thereof to admit of power being taken therefrom. i V

2;A motor vehicle power transmitting jackvcomprising a base, intermediateup rights rising from the base, oppositely disposed braces connecting the upper ends of the intermediate uprights with'opposite end I portions of the base, a shaft journaled on the intermediate uprights and provided with pulleys for receiving and transmitting power,'end' uprights rising from the base,

stays between the upper ends of theen'd and intermediate uprights, levers adjustably mounted on the end uprights and adapted to engage the rea-r axle of the motorvehicle,

and means ona set-ofbraces of the interupon the axles, end and intermediate up-.

rights rising from the base, braces and stays for the uprights, a shaft mounted-on the intermediate uprights and provided withpulleys for receiving and transmitting power,levers adjustably mounted on the end uprights and adapted to have their outer ends. engage the rear axle of the motor vehicle, and projections on, certain braces for engaging the inner ends of the levers to hold the latter in the required adjusted position.

In testimony whereof I affix my signature in presence of two witnesses, Y

NELSON STANBROUGH.
